Specification of Letters Patent.

Patented Sept. 9, 1919..

Application filed March 4, 1916. Serial No. 82,095.

To all whom it may concern.

Be it known that I, EDWARD ERIGKSON, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Heel-Beading Machines, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawing indicatinglike parts in the several figures.

My invention relates to burnishing machines and particularly to machinesused in the ornamentation of boots and shoes. In

the manufacture of boots and shoes it is customary to burnish, bead orindent lines of ornamentation upon the edges of various parts of them.It is the object of my invention to provide a machine whereby the edgesof the heels of shoes can be easily and satisfactorily ornamented.

A feature of my invention is a tool carrier having an ornamenting gageand an ornamenting tool mounted thereon. The engagement of theornamenting gage with one corner face of a heel ornaments this facewhile gaging the operation of theornamenting tool on the adjacent cornerface.

Another feature of the invention is a novel organization ofornamentingmechanism operating by percussive action on the lected for purposes ofillustration and shown in the accompanying drawings in which,

Figure 1 is an elevation of the head of the machine,

Fig. 2 is a detail, the supporting parts of the machine being removed,

Fig. 3 is a detail of aburnishing tool,

power driven by means of a pulley 3. The

head contains two sockets l and 5 opposite the inner ends of which areflattened portions 6 and 7 of the shaft :2, respectively. Theseflattened portions may be made continuous with each other, if desired.The socket 4 contains the tool shank 8 which is 50- arranged that it canreciprocate verti- #ally in the socket but is confined by a shoulder atits lower end so that it cannot fall out. The shank S carries aburnishing tool on its lower end.

The burnishing tool, shown more particularly in Fig. 3, has a body 9 inwhich there is a right and left screw 10 extending laterally from bothsides. The screw carries a disk 10 which is seated in a slot 10 in thebody. Threaded on the ends of this screw are two ornamenting plates 11which are doweled at 12 to permit their lateral adjustment with regardto the head and to prevent their turning. The dowels 12 also prevent thescrew and plates from sliding out of the head, by means of the slot 10 Aset screw 13 holds the screw 10 in adjusted position. At the bottom ofthe head 9 is the combined gage and burnisher 14. As shown in Fig. 3this gage does not cover the entire bottom face of the head 9 but leavesover-hanging portions 15 of the plates 11. WVhen a heel is presented tothe tool as in Fig. 2 the upward pressure of the work lifts the shank 8against the shaft 2 and the flattened portion 6 thus causes a rapid upand down reciprocation of the shank 8. The member 14: burnishes the endsof the heel breast and at the same time serves as a guide for the plate11 which indents a line along the outside vertical edge of the heeladjacent to the breast. The portion 15 of the plate 11 ornaments thesole above the breast at the end of the shank, the overhang permittingthe portion 15 to reach these parts of the shoe while the gage 14 is incontact with the breast.

The other lateral edge of the heel breast is treated by rotating theshoe around an axis perpendicular to its sole and applying the otheredge of the heel breast to the other side ofthe tool carried by theshank 8.

The lateral adjustment of the plates 11 permits any desired variation inthe distance of the indented line from the corner of the heel breast.

In the alternative construction of tool shown in Fig. 5 the body 16 hasthe indenting surface 17 on its lower end and has hinged to it the guideand burnisher 18. This guide and burnisher is held in adjust ed positionby a screw 19 which works against a spring 20. It will be noticed thatthere are two overhanging portions 21, one on each side of the guide 18.When this form of tool is used the shoe is rotated about alwayspresented to the same side of the gage 18.

I At the extremity of the head of the ma chine is mounted, upon ahorizontal pivot an arm 23. On the inner end of this arm is carried theplunger 24 which is vibrated in the socket 5 by the flattened portion 7.The outer end of the arm carries the tool 25. This tool is similar tothe tool shown in Fig. 5 except that a heading wheel 26 takes the placeof the edge 17 The arm -3 is so balanced that the plunger 2* is not incontact with the shaft 2 except when under the upward pressure of thework. The tool is then vibrated vertically about the pivot as center.The end of the shaft 2 carries a crenelated wheel 27 and an idler gage28 for indenting a line across the tread face of the heel as shown inFig. 4:.

Having described my invention, what I claim as new and desire to secureby United States Letters Patent is 1. A tool carrier constructed andarranged to reciprocate transversely to the work and carrying anornamenting gage and an ornamenting tool.

2. A tool carrier constructed and ar ranged to reciprocate transverselyto the work and carrying an ornamenting gage and an ornamenting toolmounted laterally thereof.

3. An ornamenting tool having a burnishing guide constructed andarranged to move across a heel edge and an adjustable ornamenting toolmounted laterally of the burnishing guide in such manner that both facesof a heel edge may be simultaneously treated.

4. An ornamenting tool comprising a burnishing guide adapted to engagethe edge of a heel breast and a laterally adjustable ornamenting toolprojecting beyond said guide in such manner that the sole edge at theend of the shank may be ornamented.

5. In a machine of the class described, a lever having a tool at itsend, said lever and its tool being constructed and arranged to permit'ashoe to be turned freely over or about while in cont-act with the tool,and means for applying percussive impulses to the lever, said leverbeing normally separated from its actuating means and shiftable toreceive percussive impulses when the work is pressed against the tool.

6. In a machine of the class described, an ornamenting tool adapted tobe percussively engaged with the Work and a relatively adjustableburnishing guide.

7. In a burnishing machine, a tool having a gage constructed andarranged to burnish one edge of a corner of a heel and a surfaceconstructed and arranged to ornament the other edge of said corner, andmeans for oscillating said tool transversely to the portion of the workbeing treated.

S. In an ornamenting machine, a tool having an ornamenting guide, anornamenting element adjacent said guide, with a portion overhanging saidguide and means for oscillating said tool with the ornamenting guide incontact with the edge of a heel breast corner whereby the ornamentingelement may treat the other edge of the corner and the sole edgeadjacent the heel breast, whereby both edges of a heel corner may beornamented.

9. In an ornamenting machine, a rotating shaft, and a member oscillatedby said shaft in a path lying across the axis of the shaft. said membercarrying an ornamenting tool.

10. I11 an ornamenting machine, a moving shaft, an ornamenting tool onthe end of said shaft, and a second ornamenting tool operated by saidshaft and positioned out side the end of the shaft in a directionparallel to the shaft.

11. In a machine of the class described, a moving shaft, an ornamentingtool on the end of the shaft, and an arm overhanging the end of theshaft carrying an ornamenting tool, said arm being operated by saidshaft.

In testimony whereof I have signed my name to this specification.
